Summary:

This study was done from 14 - 23 September 1971 in an effort to find mixed flocks in Hawaii. While a variety of birds were seen on the islands of Hawaii, Maui, Oahu, and Kauai, this preliminary study suggested that a lack of predators in Hawaii leads to a lack of alarm calls and results in a few or no mixed flocks. However, the author felt that the rarity of mixed flocks might also be so due to the high number of individual birds and food sources as opposed to a lack of predators. As a result, it was felt that more study is needed both in Hawaii and in other areas in order to determine if the absence of predation causes a lack of mixed flocks.
